PURPOSE:To perform efficient lubrication by arranging a governor above a speedometer pinion and forming an opening for the drain of the governor over where a pinion driving gear engages a governor shaft. CONSTITUTION:The governor 3 is arranged over the speedometer pinion 11. Then, the opening 12 is formed extending over the 1st gear 9 engaging at least the governor driven gear 6 of a differential gear case 1 in the area covered with the governor seal cover 7 of a differential gear case 1. Thus, the opening is only formed in the governor in this invention to drop governor lubricant drain oil near where lubrication is necessary by gravitation, so the structure is simplified and the speedometer pinion is lubricated efficiently. |
